CAR-STARTER.

SPECIFICATION forming part of Letters Patent No. 350,138, dated October5, 1886. Application filed July 17, 1886. Serial No. 20833-3. (Nomodel.)

To all whom it may concern.-

Be it known that I, DAVID JENNINGS, of Lyons, county of IVayne, in theState of New York, a citizen of the United States, have invented certainnew and useful Improvements in Car-Starters, of which the following is aspecification, reference being had to the accompanying drawings, inwhich Figure 1 is a side elevation with one wheel removed, showing partsin their normal position; Fig. 2, a like View showing pawl engaged withthe ratchet-wheel; Fig. 3, a like view showing pawl disengaged and partsin position assumed after caris started Fig. 4, a rear elevation ofstarting mechanism; and Fig. 5, a vertical transverse section taken online :r :r, Fig. 4.

Similar letters and figures of reference indicate corresponding partsthroughout the several views.

My invention relates to that class of can starters using apawl-andratchet-wheel device secured upon the axle and connected to thedraw-bar as a means of imparting the starting movement to the car.

My object is to improve the construction, durability, operation, andefficiency.

It consists of the several novel features of construction and operationhereinafter described, and which are specifically enumerated in theclaims hereto annexed.

It is constructed as follows:

A is the car-wheel, mounted upon the axle B in any ordinary manner.

0 is the bottom of the car, upon the under side of which I secure thebumper 1, provided with a longitudinal hole to receive the drawbar 2,and the perforated lug or stud 3, also receiving the draw-bar, as shown.

D is the starting mechanism upon the axle B, consisting of theratchet-wheel 4, provided with a hub, 5, upon each side of the body ofthe wheel, the whole being bored out to fit upon the axle, a frame, 6,fitting loosely upon the hubs on each side of the ratchet and providedwith a bolt, 7, to hold the frame parts together at their lower end, anda like bolt, 8,

at its upper end, and a balanced pawl, 9,

mounted upon the bolt 8, consisting of the pawl proper andcounter-balance 10, integral with each other.

11 is a yoke mounted loosely upon the bolt 8, perforated in its head toreceive the link 12, which is connected to the draw-bar 2 by the chain(or red) 13. This yoke is also provided with an eye, 14, to which Isecure one end of the spring 15, the other end being connected to thebottom of the car. This spring can also be placed around the draw-bar 2between the bumper 1 and the adjustable collar 16 upon the draw-bar. Theyoke ll, when drawn forward, lies and bears upon the pawl, and whendrawn back is not entire] y free from it.

In the drawings I show the ratchet 4 and its hubs, and also the frameparts as biscctional, and these halves as secured together by bolts.This construction enables me to mount the whole device upon an axlewithout removing a wheel. The ratchet-wheel is fastened in position uponthe axle by set-screws 17.

The draw-bar 2 is recessed or notched, as at 18, the notch receiving thelower end of the stop-pin 19, which is mounted in the bracket 20,secured. upon the platform of the car and provided with a spring and ahead, so that the pin can be raised out of the notch when desired, orwhen the drawbar is to be released to operate the starter. IVhen the pinis in positive engagement with the notch, the car is drawn without theaid of the starter mechanism.

It is operated as follows: I raise the pin 19 out of the notch 18 andstart the horses. strain then draws the draw-bar 2 longitudinallythrough the bumper, and pulls the frame 6 over toward that end of thecar until the pawl engages with the ratchet-wheel, as shown in Fig. 2.Then,as the movement forward of the draw-bar continues, the pawl throwsthe ratchet-wheel over farther forward, revolving the axle and wheels A,and thus starting the car itself forward. Then, as the draw-bar ispulled out farther, the pawl, operating somewhat eccentrically with theline of draft, is raised out of engagement with the ratchet-wheel, andthe collar 16 comes up against the inner end of the bumper, and thenthis collar takes all of the strain off from the starting mechanism andrenders the draw-bar 2 into a rigid draw-bar; also, when the pin 19 isengaged with the notch 18 the draw-bar is a rigid one. Then, when thestrain is removed or the car is stopped, the spring 15 throws all of theoperating parts back into normal position, as shownin Fig. 1. This Thereturn of parts is assisted also by the counterbalancing-weight ofthelower end of the frame 6, and to increase this assistance, and, infact, to cause these parts to return without using any spring 15, Iadd aweight to the bolt 7, as shown in dotted lines in Figs. 3, 4, and 5.

The counter-balance of the pawl is of T form with reference to the pawlitself, and its projecting ends rest against the frame parts and abovethe ratchet-teeth when the pawl is disengaged. The draw-bar 2 is alsoprovided with a collar, 22, which regulates the backward throw of thedrawbar.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a car-starter, the combination of a counterbalanced pawl, a yoke,11, fitted upon the pawl-axle and resting against the pawl and providedwith a return-spring, 15, a bipartite ratchet provided with side hubsand secured together upon the car-axle, and a bipartite main framesecured upon the ratchethubs and provided with set-screws 17 and withthe draw-bar 2, connected to the yoke 11, and mounted substantially asshown and described.

2. A car-starter consisting of an axle, a hubbed ratchet securedthereon, a frame mounted upon the ratchet, a counterbalanced pawlmounted in the frame, and a draw-bar connected to the pawl-yoke andmounted upon the car-bottom and provided with collars 16 and 22 andnotch 18, and a car-platform provided with a bumper and a stop-pin, 19,in combination, substantially as shown and de scribed. 1

In witness whereof I have hereunto set my hand this 7th day of July,1886.

DAVID JENNINGS.
